Key result
Elders identified as high risk using eight baseline factors had a higher cumulative incidence of repeated hospital admission compared to low-risk elders (41.8% vs 26.2%, P<0.0001).
Why the study?
Do eight easily ascertained risk factors identify elders at high risk for repeated hospital admission?
Population
5,876 non-institutionalized U.S. civilians aged 70 years or older in 1984
Comparison
High probability of repeated admission based on… vs Low probability of repeated admission (Pra < 0.5)
Design
Cohort
Follow-up
4 years (1985-1988)

May support identifying high-risk elders for monitoring; leaves open whether interventions reduce repeated admissions.
Cohort (n=5,876)
Yes
Do eight easily ascertained risk factors identify elders at high risk for repeated hospital admission?
Absolute Event Rate: 41.8% vs 26.2%
p-value: p=< 0.0001
Eight easily ascertained risk factors can identify elders at high risk for repeated hospitalization and mortality over a 4-year period.
Boult et al. (1993) conducted a cohort in Risk of repeated hospital admission (n=5,876). High probability of repeated admission (Pra ≥ 0.5) vs. Low probability of repeated admission (Pra < 0.5) was evaluated on Cumulative incidence of repeated admission (p=< 0.0001). Elders identified as high risk using eight baseline factors had a higher cumulative incidence of repeated hospital admission compared to low-risk elders (41.8% vs 26.2%, P<0.0001).
